Abstract
Glycidyl ethers of polyhydric phenols having an average of more than one 1,2-epoxy group per mol. are hardened by mixing them with a complex formed by heating a resole with a polyamine, the complex having at least two replaceable H atoms per mol. forming part of the amino or imino groups. Polyamines specified are diethylene triamine ethylene diamine and the resoles are obtained by heating phenol and formaldehyde in presence of hexamethylene tetramine or by heating octyl phenol and formaldehyde in presence of ammonia. In Examples (1) 100 gs. phenol and 78.2 gs. 37 per cent formaldehyde were heated to 80 DEG C. in presence of 2.3 gs. hexamethylene-tetramine until the formaldehyde was all reacted; the product was dehydrated and mixed with 36.5 gs. diethylene triamine and the mixture was heated at 100 DEG C. for 15 minutes; a viscous liquid resin was obtained. Equal weights of the resin and an epoxy resin were dissolved in methyl isobutyl ketone, toluene and cyclohexanol and "Cellosolve" (Registered Trade Mark) and the solution, applied to steel and tin plates, dried tack-free in 2 hours.
